In the callers of start-process, which assume that an executeable shell
script can be used as the command argument.

By (optionally) invoking the command via a shell. This allows
integration of unix style commands inplemented as executable shell
scripts with Win32 emacs. At the moment I handle this on a case by case
basis with advice, but it would be useful to allow a more general
wrapper.
